Thank you to all who responded on and off-list to my recent request for additional comment on policy options for reporting high resolution ground-based imagery of Earth satellites. I believe that there is general agreement in favour of Option 2, with the requirement that raw frames be made available. Option 2 is described here: http://satobs.org/seesat/Aug-2010/0134.html The proposed draft rules, as appended to this message, are based on those in the above message, with some changes, especially to the raw frames requirements. I am open to suggestions for improvement in content and clarity. I have very little technical knowledge of this field, so I am especially interested in suggestions for improvement from imagers. PLEASE NOTE: The final rules that result from this consultation will be retroactive to the present time: 2011 May 16, 11:36 UTC. Ted Molczan Admin Draft rules for reporting high resolution ground-based imagery of Earth satellites SeeSat-L welcomes the reporting of high resolution ground-based imagery of Earth satellites, subject to the following required supporting information: ID of object: COSPAR, USSTRATCOM catalogue number, common name Description and dimensions of object (metres), if known. Observing site location: latitude, longitude, altitude, to nearest 100 m Date/time of obs: UTC. For single frames, report time to nearest second. For video, report start time and duration to nearest second. Range to object: km Telescope: make/model/aperture Camera: make/model Tracking method: hand-guided, or mechanical (make/model) Data acquired: total duration, frame rate, exposure per frame, resolution & bit depth of raw data Processing: describe the process of frame-selection and/or image-processing used to obtain reported results. Raw image frames: Results consisting of one or more frames selected from a longer series of frames, whether image-processed or not, must be supported by at least 60 seconds of the complete set of raw frames centred on the time of the results, i.e. 30 s before and after. By raw frames is meant the data exactly as taken from the camera that formed the input into the process of frame-selection and/or image-processing that produced the result. If the result is displayed on a web site, then a link to the raw data should be located in close proximity. An alternative would be to place a statement that the data is available upon request, in close proximity to the results. _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
